After the hard-earned funds for their expensive high school class trip are stolen, sophomore Yuichi and his four best friends are kidnapped by Manabu, a surreal character from a creepy late-night anime show. The mischievous Manabu challenges the students to a series of mind games that the five must decipher and outwit in order to win back their trip funds, uncover the thief, and pay off a huge and mysterious debt.
But at this rate, they're all 
sure to fall straight into Hell.
.لكن على هذا الحال، سيقعون في الهلاك جميعًا
Aber jetzt …
Pero a estas alturas…
Pero a estas alturas…
Mais au point où ils en sont,
Ma, ormai, sono certi di andare dritti all'Inferno!
Mas agora...
Но только не сейчас.
